Application filed August 3, 1907. Serial No. 386,910.

T all 'wlwm t'tmay concern:

Be it known that I, O'r'ro Soimnnnnr, a citizen ,of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented certain new and useful Improvements in Toasters; and I dodeclare the following to be a fiill, clear,

i and exact description of the invention, refgasolene stove or oilstove, and which may be used also on stoves using other kinds of fuel,the present invention however, being designed more particularly with aview to using it where circular burners are used.

The object of the invention primarily is to provide a toaster which willhave. the great-' est efficiency with the minimum consumption of fueland yet be adapted-to be constructed at the minimum cost,the objectspecifically being to construct the toaster of the fewest number andinost simple forms of parts in such manner as to eliminate supplementaryparts which have heretofore been required for the distribution of heat,a further object beingto provide a toaster which may be used for eitherheating or cooking purposes as may be desired, and further to provide atoaster that will be stable in construction and durable and economicalin use.

.Referring to the drawings Figure l is a side elevation of the toasterconstructed substantially in accordance with thei'nvention; Fig. 2, avertical sectional view thereof on the line A A in Fig. 1; Fig. 3, atopplan View; Fig. 4, a bottom plan viewv partially broken away; Fig. 5, afragmentary sectional view as at the line B in Fig. 3; Fig. 6,,

a fragmentary sectional view as on the line C G in Fig. 2; and, Fig. 7,a perspective .view of the deflector which may be con nectcd removablyin the combustion chamber of the toaster.

Siniilar reference characters in the scveral figures of the drawingsdesignate like elements or features of construction.

The improved toaster comprises a frame having a base a which ispreferably rectano gular in plan and has a central circular openingaround which is an upturned flange b, the extremities of the base havingfour straight edges, the edge portions being curved upwardl to formheads 0, and downwardly to form ips a, each bead having two guide holesd and al' in the tops thereof.

The combustion chamber has a wall composed of a single thickness ofmetal and is circular, one end being greater in diameter than the otherend, and the larger end placed V upon the base a and extending about theflange 6 whereby the wall is retained in central position on the base.The wall has four separate imperfora te portions e, f, g, h which areopposite to the middle portions of the, straight beaded edges ofthebase, and between the imperforate portions are four portionsliavingperforations, asi, j, 7:, Z,

the perforations being. in four groups and.

the groups being opposite to the corners of the base. The perforationspermit the oxygen of the atmospheric air to mix with the flames so as toaid in producing more perfeet combustion than'w-ill take place behindthe imperforate portions of the wall, so that the perforate portionswill become heated to redness and therefore radiate a. higher degree ofheat than will be radiatedfrom the -in'iperfora te portions which do notbecome heated to the degree of redness with an economical rate ofconsumption of the fuel.

I Each imperforate portion of the wall has'a projection m on its innerside, somewhat near the top thereof which may suitably be struck up fromthe metal.

A square top n isprovided which has a I central circular depression 0fitting into the top of the, wall of the combustion chamber,

whereby the two elements are joined to-I' gether, the top having fourdownwardly ex tending flanges p, each flange having two apertures q andq.

The toaster has four pairs of supports upon which to place the bread orother article to be toasted, and are arranged at the middle portions ofthe straight beaded edges of the base and connected thereto andextending upward to the top and connected thereto, each pair of supportsbeingcomposed of a single piece of wire having two slightly inclinedmembers 1' and s, at the bottoms of which are slightly inclined crossbars 1* and s to which are joined upright members at and t, the latterextending has four flanges 20 turned up, and between each two flanges aspring finger y is formed which also extends upwardly, and the springfingers are adapted to engage the wall of the combustion chamber at theinner sides of the iniperforate portions and also engage the projectionsm for renio'vably holding the deflector, the four Iportions of the platew on which the flanges a: :are formed, having no conta ct with the, wallso that some of the heat of combustion'may rise freely above the plate walong the portions of the wall that has the perforations therein, and bythe use of the dellec'tor the heat will be deflected so that the top nwill. not become excessively hot and will perinit articles to be warmedor kept warm upon the top of the toaster, while on the other hand if thedeflector be removed, the top 12 will become sufliciently hot to permitof cooking be done thereon.

In practical use four slices of bread or similar article of food may beplaced on the toaster at one time. Each slice as indicated by a andshown by dotted lines in Figs. 1 and 3 is to be placed on a pair ofinclined members 1' and s so as to lean against the members r and s, andthe slice will be relatively closer atits middle portion to theimperforatc portion of the wall of the combustion chamber than its endportions will be to the perforate portions of the wall. ()nly suflicientheat will be generated by proper regulation to suitably heat theimperforatc portion without scorching the article, and the degree ofheat necessary to toastfthe slice uniformly will be automaticallyregulated at the perforate portions which recede from the slice byreason of the higher degree of heat resulting from more perfectcombustion, due to the free admixture of the ignited gases passingthrough the-perforations with thc'atmospheric air, and the area of metalbetween the perforations being less than the areaof the imporfora'teportions per square inch permits the heat of-combustion to raise thetemperature of the perforate portions to a higher degree than that ofthe imperforate portions, so that the heat will be approximately uniformon all portions of the surface of the slice of bread, notwithstandingthe end portions are not as close as the middle ortions-to the wall ofthe combustion cham er. i

When the deflector is used the heat will be deflected to some extentoutwardly beyond the top a so that if a pan be placed upon the top, thetoasted bread or other articles or crackers may be heated on the plateor kept Warm, and if it be desired to make coffee or tea while. toastingthe bread the deflector-may be removed sothat all of the heat will risedirectly to the top a and permit of-various cookin operations thereon.

Having thus descri ed the invention, what is claimedas new is i v 1. Ina toaster of the character described, the combination with an aperturedbase, a top, and supports connected to the'hase and also to the top, ofa combustion chamber wall on the base and in engagement with the top,the wall comprising imperfprate portions and alternate perforateportions, and a deflector supported against the 1nner side of said wallin proximity to said top and having portions that engage saidimperforate portions and having also portions that extend across saidperforate portions free from contact therewith.

2. In a toaster of the character described, the combination with a base,a top, and sup:

ports connected to the base and the top, of a combustion chamber wall onthe base and in engagement with the to and having four projectionsformed on the lnner side thereof,-
